MICHIGAN, ASSIGNOR, BY -IMESNIE ASSIGN- OF IICBIGLN FRONT PLATE CONSTRUCTION FOB TRAY COHPABTHENTS appumm nieu october i4, 1929. serial No. 399,544.

This invention relates generally to refrigerating a paratus and refers more particularly to tige cooling units thereof.

VOne of the essential objects of the invention is to provide the cooling unit with a front piece that surrounds and serves as a border or framing for the tray compartment of the unit, that conceals the expansion coils and suspension brackets for the cooling unit, and that constitutes a common mountingor sup rt fora temperature control dial and an indicatin thermometer.,

Another 0% ect is-to provide a front piece of this ty that is neat in a vpcarance and that may manufactured an installed at a com arativel low cost.

ith the a ve and other objects in view the invention consists of certain novel features of construction, combinations andarrangements of parts that will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a front elevation of a refrigerator cabinet embodying my invention and showing the main door t ereof 1n open position' Figure 2 is a verticalsectional view taken on the line 2-2 of Figure 1;

Figure 3 is a cross sectional view taken Von' the line 3-43 of Figure 2;

Fi re 4 is an enlarged fra entary front elevagtrilon of the freezing unitbnt piece and associated parts;

Figure 5 is an enlarged fragmentary vertical sectional view through the Afood compartment door and freezing unit.

Referring now to the drawing, 1 is a cabinet designed for refrigerating apparatus and having vertically spaced -machine and food compartments A and B res ectively opening outwardly through the the cabinet and provided with suitable doors 3 and 4 respectively. Preferably the machine compartment A contains the compressor, motor, condenser, fan land, in some instances, the expansion valve (not shown) of suitable refrigerating apparatus and receives air from the atmosphere through suitable louvers 5 in the door 3, while the food com- .asa

ont wall 2 of partment B contains the cooling unit 6 and 1s effectively sealed by a gasket 7 on the front wall 2.

Preferably the cooling unit 6 is suspended by hangers 8 and 9 from the top wall l0 of the cabinet and comprises a tray compartment 11, a layer 12 of insulating material, and rcfrigerant expansion coils 13 and 13. Any suitable`means such as the tubes 14 may be used to conduct refrigerant between the lcoils -13 and 13 and the condenser and compressor within the machine compartment A.

' As shown, the ice tray compartment 11 opens outwardly adjacent the door 4 and is lprovided at its open end with a marginal flange 15 that projects laterally therefrom in substantially parallel relation to the door and serves as an ing unit front piece 16. Preferabl adjacent edges 17 and 18 respectively of the fliont piece and ilange are secured together and the joint therebetween is covered by a gasket 19 designed to be` engaged by the door 4 when closed -to seal the tray compartment 11. In the present instance the front piece 16 serves framing for the tray compartment 11 and conceals the coils 13, 13', and the hangers 8 and 9. Preferably the front piece has a forwardlyaextendng flange at its upper edge secured to the top wall 10 of the cabinet and is provided at opposite upright edges thereof adjacent said flange with lateral wing portions 2O and 21 that serve as framings for two refrigerator instruments such as the thermometer 22 and a temperature c'ontrol dial `23. As illustrated, these instruments are mounted in openings 24 and 25 respectively in the wing portions and 21, however the manner. of mounting the same and the construction and design thereof are not claimed in this application.

While it is believed that from the foregoing description the nature and advantages 0f the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall Within the scope of what is claimed.

attaching flange for a cool- Y 2 i teams What I claim as my invention is:

sf 1. In combination, an ice tray compartment having an open forward'fend and provded at said end withv a marginal laterally 5 extending flange, and a front piece for the compartment comprising a substantially flat plate having an opening receiving the lateral flange and having late-rally extending substantiall iat wing portions provided with openings or receiving refrigerator instruments.

2. In combination, an ice tray compartment having an open forward end and provided at said end with a flange member, andl a front piece for the compartment comprising a substantiall flat plate havin an opening through whic access may be lad to the interior of the ice tray compartment and having laterally extending portions extend- 2 ing in opposite directions away from the ice tray compartment, one of said laterally'ex-- tending portions being provided with an opening for receiving a temperature control device.

Intestimony whereof I aix my signature.
